How do I know if I have PDB or CDB?
Starting Oracle 12.2 sys_context(‘USERENV’,’DB_NAME’) will show the name of the Database in CDB$ROOT and the name of the PDB inside the PDB.
How do I know if PDB is compatible?
Checking the Compatibility of the Unplugged PDB with the Host CDB. Before starting the plugging operation, make sure that the to-be-plugged-in PDB is compatible with the new host CDB. Execution of the PL/SQL block raises an error if it is not compatible. [if cdb2 is not started up, start it up now.]
How do I transfer PDB from one CDB to another?
Plugging the Unplugged PDB: AS CLONE MOVE Method Create and define a destination for the new data files, use the data files of the unplugged PDB to plug the PDB into another CDB, and then move the data files to another location. Plug the PDB into the CDB and move the data files to a new location.
